“Hard launch @alanbyrne10,” she wrote, revealing her new boyfriend's name.
“Felt cute, will defo delete later,” the caption continued.

True to her word, the 39-year-old quickly removed the post from her Instagram feed.
Earlier this month she posted a snap of her new fella, doodling over his eyes in a bid to conceal his identity.
“Soft launch,” she captioned the picture.
McNally revealed in May that she was dating the Dublin model and DJ.
During an Instagram Q&A, Joanne joked that she was mortified to admit that she's no longer single.
“I’m actually seeing someone,” the 39-year-old shared.
“I met an Irish guy on Raya, he’s sound and we’re like, dating or whatever.”
“But obviously I’m going to block him from seeing this video because I don’t want him to know I’m acknowledging we're dating, because (it's) embarrassing,” she joked.
Joanne joked that she and her mystery man were basically “engaged” because they were not seeing anyone else at the time.
She continued: “It was basically like, ‘Are you riding anyone else?’ ‘No. Are you riding anyone else?’ ‘No.’
“He was like, ‘Let’s just ride the wave’ and I guess I’m the wave.”
